which the locking flange or interlocking instrumentality of the overlapping shingle may engage and interlock.

A further object of the invention is to utilize the method disclosed to prevent the lifting of the exposed butt of the shingle, as so often happens in wind and rain storms, and thus substantially eliminate or minimize the possibility of the leakage of rain through the roof or wall, and at the same time to minimize the possibility of fracture to the shingle base that might be caused by such forced lifting due to storms.

A further object of the invention is to provide instrumentalities for accomplishing the above objects which are simple in structure and use, efficient when applied, and economical to manufacture.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts together with the novel method employed in the interlock in accordance therewith, all as will be more fully hereinafter set forth, as shown in the accompanying drawing, and finally pointed out in the appended claims.

Referring to the drawing:

Fig. 1 is a diagrammatic top plan view of a construction and arrangement of a plurality of shingles in assembled relation showing an arrangement for accomplishing the object of, and embodying my invention.

Fig. 2 is a sectional view on line A-A in Fig. 1 showing the interlocking construction employed in the invention".

Fig. 3 is a perspective view of a clip that may be used to secure the free ends of the sealing layer with the base.

Fig. 4 is a fragmentary perspective View of an edge portion of a shingle showing the clamp or clip secured thereto.

The same part is designated by the same reference character wherever it occurs throughout the several views.

In accordance with my invention, I employ a base member 10 of a plastic composition impervious to water such as asphalt or other similarv (Cl. 10H) composition. Mounted on and secured to this base there is provided a non-corrosive metallic element 11, such as copper or Monel metal, or enameled metal of a length less than the base,

and of a Width equal to, or slightly less than 6 the base,A and having one end extending over and under the base in the form of a flange as at 12. This flange constitutes one element of the interlocking instrumentality. This ilange is separated from the base member so as to leave an un- 6 occupied space as at 13, for the reception of a sealing layer hereinafter described.

The sealing layer 14 is also impervious to Water, and is secured or cemented to the base in any practical manner throughout a greater portion of its length and width. Adjacent the joint between the metallic element 11 and the base member 10, as at 15, and extendingfrom therebeyond to the extremity 16 of the sealing layer, the sealing layer is free from cementing attachment with the base or metal. The lateral portions of the sealing layer however may be secured with lugs 17 andI 18, that may be integrally formed or otherwise connected to or with the metallic element in any suitable practical manner.

The lugs 19 and 20 may be integral with the metallic element, and bent over the edge and under and against the under surface ofthe base member 10.

From the construction shown it will be apparent that the free ends of the sealing layer is held against upward lifting, and that the rnetallic element is doubly secured at this particular interlocking joint to the base, first by the cement that holds the metallic element to thevbase, and second by the lugs 19 and 20 that are bent over and under the base.

The interlocking flange 12 is bifurcated as at 21 to form furcations 22 and 23, so that when the shingles are placed in overlapping courses as is the common practice with ordinary shingles, the furcations may be slipped under the sealing layer and avoid coming into contact with the lugs or clips that hold down or' secure the free ends of the contiguous sealing layers of the underlying course.

The sealing layer may be made more resistibl`e than the base, so that if the lugs 17 and 18 are not used, the sealing layer will be of such rigidity, that the free end of the sealing layer and under which the interlocking flange is secured is practically non-frangible. It will also be observed that if the lugs or clips are omitted,

it will not be necessary to bifurcate the interlocking flange 12 that extends transversally oi.' the shingle.

The clip 24 shown in Figs. 3 and 4 may be used instead of the lugs 17, 18, 19 and 20 if desired, to secure the free ends of the sealing layer to the base.

It is believed that the application of the shingles as a' whole will be clear, in view of the foregoing description, which has been given in connection with that of the construction of the same.

It is to be understood that the structure shown is for the purpose of illustration only and that variations may be made 'without departing from the spirit and scope of the invention as deiined by the appended claims;

What I claim as my invention and desire to secure by United States Letters Patent is:

1. A shingle of the type'set forth including an impervious base, a metallic element thereon of less length than the base and having integrally formed therewith an interlock flange extending.

transverse the underside of the base but separated therefrom and forming therewith an unoccupied space adapted to receive a terminal portion of a sealing layer, a sealing layer secured to the base throughout a greater portion of its length and width, but free from attachment with the metallic element and the base to form a counterpart engaging element to receive anl interlock flange that may engage thereunder.

2. A shingle of the type set forth including a base, a metallic element thereon of less length than the base having integrally formed therewith a bifurcated interlock ange transverse the underside of the base and forming with the base y an unoccupied space adapted to receive a terminal portion of a sealing layer. a sealing layer secured to the base throughout a greater portion of its length and width, but tree from attachment with the metallic element and the base and adapted to receive an interlock flange that may engage thereunder, and lugs strengthening -the free lateral ends of the sealing layer.

3. A shingle of the type set forth, a base portion, a metallic element thereon of less length than the base, an interlock flange dependent from the metallic element and separated from the base, asealing layer connected to the base portion, but free therefrom at one of its ends with both the base and metallic element to match with and to receive the interlock ange of an overlapping shingle thereunder.

4. A shingle of the type set forth including a base, a metal element thereon of less length than the base having integrally formed therewith a bifurcated interlock flange transverse of and on the underside of the base, and forming therewith an unoccupied space adapted to a terminal portion of a sealing layer, a sealing layer attached to the base throughout a greater part of its length and width, but free from the metal element and the base sovas to form a recess having a crosssection to receive an interlock ilange. and lugs dependent from the metal element reinforcing the attachment of the metal element with the base of the said shingle, and also the sealing layer Y attachment with the metal element.

5. A shingle of the type set forth including a base, a metal element thereon of less length than the base having formed therewith a bifurcated interlock ange transverse of and on the underside of the base, and forming therewith an unoccupied spacev adapted to receive a. terminal portion of a sealing layer, a sealing layer attached to the base through a greater part oi' its length and width, but free from the metal element and the base to establish means to effectively receive and maintain an interlock flange, and clips connecting the free lateral ends of the sealing layer with the base portion.
